Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With annotations only covering the safety profile, the description adds substantial behavioral context: card is created 'no AI', the suggestion's text is NOT changed, nothing is published, the already-added failure mode, and the return shape. These are exactly the side-effect details an agent needs before invoking a mutating tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

One dense but well-ordered paragraph that front-loads the action and effect, then layers the overrides, non-effects, failure mode, and return value. No filler sentences; each clause carries distinct information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, and the description compensates by naming the returned { suggestion, content } pair. It also covers side effects and failure conditions thoroughly, but the unexplained brandId parameter leaves a minor hole in an otherwise complete picture.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description carries the burden and it only partly compensates: scheduledDate is well defined (YYYY-MM-DD or ISO, overrides the suggested date as the planned date) and suggestionId is implied by the failure condition, but brandId is never mentioned or explained.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource (accepts a brainstorm suggestion) and spells out the concrete effect: creating a content card in the idea column from title/idea/funnel stage, then flagging the suggestion as added with contentId. It reads clearly against siblings like dismiss_brainstorm_suggestion, list_brainstorm_suggestions, and create_content.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a clear usage context plus a failure precondition ('Fails if the suggestion was already added') and notes scheduledDate overrides the suggested date. It does not explicitly contrast with alternatives such as dismiss_brainstorm_suggestion or create_content, so the routing guidance is implied rather than stated.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
